COMBINATION PADLOCK.

Specification of Letters Patent.

Patented May 7, 1918.

Appueation mea .my 2a, 1917. seran No. 182,991.

To all whom t may toucern:

Be it knownk that I, GEORGE TAVRA, a citi-k zen of the United States,residing at Eureka, in the county of- Humboldt and State p, ofCalifornia, have invented .certain new and useful Improvements invCombination-Padlocks; and I do hereby declare the following to be afull, clear, the invention such as will enable others skilled in the artto which it appertains to make and use the same.

The invention relates pad lock.

The object of the present invention isy to provide a simple, practicaland efficient permutation or combination padlock of strong,

durable and inexpensive construction adapted to be easily operated byany one understanding the combination and equipped with a relativelylarge number ofrotary rings having notches adapted to be brought intoline and coperating with lugs of an arm so that it is necessary toarrange all of the recesses in alinement simultaneously in order toeffect an opening of the lock.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the'drawing: y Figure 1 is a perspective view'y of a combinationpadlock constructed in accordance with this invention. y.

Fig. 2 is a longitudinal sectional'view of the same, the `'relativelymovable shackle section being unlocked.

Fig. 3 is a transverse sectional view of the padlock. t

Fig. 4 is a detail of the rotary rings.

Like numerals of reference designate corresponding parts in the severalfigures ,of the drawing.

In the accompanying drawing, in which is illustrated the preferredembodiment of the invention, `the combination vpadlock comprises in itsconstruction a shackle composed of lixed `and relatively movablesections l and 2, the relatively fixed section lbeing seperspectiveviewfof kone and exact description ofto aY combination` cured to one endof a spindle 3 which has its other end 4 threaded for the receptionofthe relatively movable shackle section 2. The relatively movableshackle section 2 is provided with a threaded opening 5 for thethreadedy end 4 of the spindle, and it is adapted to be rotated toarrange it in' aline ment with the relatively fixed shackle sec-y tion,as illustrated in Fig. A l, and also to swing it away from indottedlines in Fig. 1. yThe threaded con` nection" betweenthe section 2and the spindle provides a pivotal or swinging movement for the saidsection 2 and the threaded opening 5 preferably'extends inwardly fromthe inner face of the section 2 and terminates short of the outer facethereof. The shackle sections are preferably provided with enlargedcircular ends 6 and 7 and are reduced beyond the said ends.

The 'end 6 is provided with a slot 8 which registers with a longitudinalgroove 9 in the bottom portion of the spindle to receive an inner arm 10of a locking member 11 having an outer arm 12 and conforming'totheconfiguration of the adjacent shackle section l. The outer arm 12extends through an opening 13 in the section 1 and is adapted tokproject intoy an opening 14 in the section 9.

when the said opening 14 is arranged in alinement with the opening 13.When the` outer arm is engaged in the opening 14, the

said position as shownI section 2 is locked against relative rotarymovement, and when the' arm 12 is with"- drawn from the opening 14 thearm 2 is adapted to be rotated on the end of the spindle and it may bescrewed on or oil" the same- 4k -close the padlock.

y The inner armlO is provided with recesses 15 forming intervening lugs16 andy of rings 17, The rings are adapted to receive flanges 16aprovided with notches 18. mountedffor rotary movement on the V.spindlethe same into and out of and are provided with letters or'other char- 'lacters and they are capable ofrotary movement -to aline the notches 18to permit the intervening lugs formed by the recesses 15 to pass throughthe notches of the flanges 16a. When one'or more of the flanges are outof alinement the locking member will be held against movement and as therecesses 15 form a plurality of lugs, each cooperating with one of therings, it will be impossible for anyone to ascertain the posi-Y tion ofthe recesses by the pressure of the locking member on the same anditwill not be possible to operate the rings successively and out ofengagement with the relatively movable shackle sectipn by the slidingmovement of the innerarim and a plurality of vringsk mounted on thespindle and having without a knowledge of the recesses and means forengaging the inner arm of the move the locking member outwardly by astep by step movement. liile letters are shown to indicate the positionof the rings, numbers may of course be used.

The spindle is providedv with nal slot 19 and the inner arm ofthelocking member carries a pin 2O operating in the slotfor limiting theinward and outward movement of4 the said locking member to prevent thearm from being entirely withdrawn from the opening of the relativelyfixed shackle section. A washer 21 is shown arranged between the ends ofthe pivoted shackle section 2 so that the turning of the movable sectionof the `shackle will not change the position of the rings.

` What is claim is:

1. A combination padlock of the class de-4 scribed including a shackledivided at the outer portion and composed of relatively fixed andmovable sections, a spindle fixed to one of the sections and forming aypivot for the other section, means for holding the pivoted sectionagainst sliding movement on the spindle, a locking member located at therelatively fixed section and conforming to the configuration ofandvfitting against the same and extending to the outer end theref of,said locking member being provided with an arm of a length to extendbeyond the `fixed section and engage the relatively movable section forholding the same against movement, said locking member being alsoslidable outwardly to release the relatively movable, shackle, and meansfor locking the said locking member against such outward slidingmovement.

`ZA combination padlock of the class de scribed including a shackledivided at the outer portion and composed of relatively fixed andmovable sections, a spindle secured to one'of the sections and forming apivot for the other section, means for holding the pivoted sectionagainst sliding movement on the spindle, against the relatively fixedsection and provided vvitli inner and outer arms, the inner arm slidableinwardly and outwardly along the spindle and carrying the locking memberand the outer arm being carried into a longitudia locking memberfittingl ylocking ,rnemben 3. A combination padlock of' the class de--scribedincliiding-a shackle divided at the the relatively fixed sectionand provided with innerand outer arms, the inner 'arm slidable inwardlyand outwardly along the spindle and carrying the locking member and theouter arm being carried into and out of' engagement with the relativelymovable shackle section by the sliding movement ofv the inner arm, saidinner arm being provided at intervals with recesses forming interveninglugs,jand a plurality of rotary rings mounted on the spindle andprovided with flanges operating'in the recesses and having notches forthe passage of thelugs.

v4L. A combination padlock of the class described including a shacklecomposed of relatively fixed and movable sections, the relatively fixedsection being provided with an opening, a spindle fixed tothe relativelyfixed section and having a longitudinal groove extending Vinwardly fromthe said opening, saidl spindle being also 'provided with a longitudinalslot, a'locking member provided with means for engaging the relativelymovable shackle section and having an armv slidable in the groove andpassing through the opening 'of the relatively fixed section, said armbeingprovided at inter-f In testimony whereof I ax my signature inpresenceof two witnesses. l y GEORGE TAVRA?
